Using Eyes?	Can't Post

I have what should be a pretty basic patch but is becoming unwieldy as it scales. In short, I have Eyes watching a 3x6 area, which should get passed to a movie player to trigger a unique clip for each individual square (18 unique clips). The only way I have been able to do this successfully is to have 18 sets of Eyes watching a particular row/column which triggers a clip on entry, but performance takes a pretty large hit and I'm a fan of doing things simply. As nearly as I can figure there is no Calculation actor that would allow If/Then logic, which I could then use to parse hit col/row to pass to a movie player. Is there any better way to do this? Any suggestion would be invaluable.

Can you not "crop" the video into a number of sections and then use a "calc brightness" actor on each section to set a threshold to register a change?

Yes, what you are proposing is a little difficult with Eyes. It's really designed to follow things around, not so much to trigger on entering and leaving areas as you are trying to do.

Really a different sort of actor is required that breaks areas into chunks and measures the brightness and triggers upon reaching a threshold. All I can offer at this point is to add this as a feature request.

Best Wishes,
Mark

It sounds like we're trying to do a similar thing. I've cropped the space and am using Eyes to detect lights in different areas which then trigger short movie clips. I'm wondering if there is any way of doing this to respond to colours so there can be a choice of movie clips depending on the colour in the cropped area?

Any help would be appreciated, thanks.

Hi

Go to this thread
http://forum.troikatronix.com/...workshop_Blog_P2345/

and download the patch "eyesplusplus", the third scene (colortrack) is exactly what you are looking for.
